Thereby, the insertion of the locking protrusion 42 with respect to the insertion portion 76 is allowed from the insertion direction in a state where the base member 40 is in the insertion posture. Further, a distance W3 between the front end surface (contact surface) of the protruding edge portion 74 of the locking receiving portion 70 and the protruding end of the restricting portion 78 is the thickness W1 of the curved portion 55 of the locking protrusion 42. It is set smaller. As a result, when the base member 40 is in a fixed posture with the locking projections 42 inserted into the insertion portions 76, the restricting portion 78 contacts the curved portion 55 of the locking projections 42. As described above, the separation of the locking projections 42 and 42 from the insertion portion 76 is restricted. In the embodiment, as is apparent from FIG. 10, the gap W3 is less than half the thickness W1 of the curved portion 55, so that the locking projection 42 is inserted into the insertion portion 76. At the initial stage of rotation in which the base member 40 is slightly rotated from the insertion posture, the disengagement of the locking protrusions 42, 42 from the insertion portion 76 is regulated.

That is, the fixing portion 43 is aligned with the fixed portion 71 by setting the base member 40 to a fixed posture, and is fixed to the fixed portion 71 by rotating the fixing tool 44 to the locking position.

(Operation of Example)
Next, the operation of the pachinko machine P according to the embodiment will be described.

  When attaching the base member 40 to the installation member 30, first, the left end side of the base member 40 where the locking protrusions 42 and 42 are provided is brought close to the rear side of the installation member 30, and the base member The base member 40 is set in the insertion posture by separating the right end side provided with the fixing portion 43 in 40 from the rear surface of the installation member 30 from the left end side (FIG. 11). Then, in a state where the base member 40 is held in the insertion posture, the respective locking protrusions 42 and 42 provided on the base member 40 are inserted into the insertion portions 76 provided on the installation member 30 (FIG. 12). When the locking protrusions 42, 42 are inserted into the insertion portion 76, the first intermediate ribs 59, 59 provided on the base member 40 are positioned between the locking receiving portions 70, 70 so that the upper ribs 57 is positioned above the upper contact portion 77 and the lower rib 58 is positioned lower than the lower contact portion 77, so that the locking protrusions 42, 72 is positioned in the vertical direction.

  Then, when the locking projections 42 and 42 are appropriately positioned with respect to the locking receiving portions 70 and 70, the curved portion 55 of the locking projection 42 is brought into contact with the contact surface 78 </ b> A of the restricting portion 78. By inserting the locking protrusion 42 into the insertion portion 76, the distal end of the curved portion 55 is smoothly inserted without strongly contacting the end of the locking receiving portion 70. Then, when the locking protrusion 42 is properly inserted into the insertion portion 76, the curved portion 55 is fitted to the upper receiving portion 77 and the lower receiving portion 77 as shown in FIG. The curved portion 55 comes into contact with the receiving surfaces 77A of the both receiving portions 77, 77.

  When the insertion of the locking projection 42 into the insertion portion 76 is completed, the base member 40 in the insertion posture is rotated to a fixed posture in which the right end is close to the installation wall portion 31 of the installation member 30 as shown in FIG. At this time, the locking projections 42 and 42 are rotated in a state where the curved portions 55 of the locking projections 42 and 42 are in contact with the receiving surfaces 77A of the upper and lower receiving portions 77 and 77, respectively. Thus, the base member 40 rotates smoothly and stably from the insertion posture to the fixed posture while the bending portion 55 is in sliding contact with the receiving surface 77A. In addition, since the restricting portion 78 is in contact with the curved portion 55 of the locking protrusion 42 inserted into the insertion portion 76 in the insertion posture, the base member 40 is initially rotated from the insertion posture toward the fixed posture. At this stage, detachment of the locking protrusion 42 from the insertion portion 76 is regulated, and the left side of the base member 40 is detached from the installation member 30 while the base member 40 is rotated from the insertion posture to the fixed posture. This prevents the base member 40 from rotating stably.

  When the base member 40 is rotated to a fixed posture, as shown in FIG. 13, the front ends 55 </ b> A of the curved portions 55 of the locking projections 42, 42 are front end surfaces of the protruding edge portions 74 of the locking receiving portions 70, 70. The locking projections 42 and 42 and the locking receiving portions 70 and 70 are appropriately locked. As a result, the left end side of the base member 40 is restricted from being separated rearward from the installation member 30. The curved portions 55 of the locking projections 42 and 72 are held in the fitted state with the upper and lower receiving portions 77 and 77, and the restricting portion 78 is in contact with the curved portions 55. Positioning of the base member 40 with respect to the member 30 in the left-right direction is appropriately achieved. The first intermediate ribs 59, 59 provided on the locking projection 42 are positioned between the pair of locking receiving portions 70, 70 in the vertical direction with respect to the locking receiving portions 70, 70. The upper rib 57 of the locking projection 42 is positioned above the upper receiving portion 77 and can be locked in the vertical direction with the upper receiving portion 77, and the lower rib 58 is Since it is positioned below the lower receiving portion 77 and can be locked with the lower receiving portion 77 in the vertical direction, the base member 40 can be properly positioned in the vertical direction with respect to the installation member 30.

  Then, the base member 40 in a fixed posture is appropriately positioned with respect to the installation member 30 by the locking protrusions 42 and 42 and the locking receiving portions 70 and 70, and the fixing portion 43 of the base member 40 is Since the base member 40 is aligned with the fixed portion 71 of the installation member 30, the base member 40 is fixed to the fixed member 71 by fixing the fixing portion 43 to the fixed portion 71 by the fixing tool 44 attached to the fixing portion 43. The right end is positioned and fixed. The base member 40 can be detached from the installation member 30 by releasing the connection by the fixing tool 44 and rotating the base member 40 backward from the fixed posture to the inserting posture.

  According to the pachinko machine P of the embodiment configured as described above, the locking protrusions 42 and 42 provided on the base member 40 are provided on the installation member 30 in a state where the base member 40 is held in the insertion posture.

The base member 40 can be smoothly and stably rotated, and the workability of fixing the base member 40 to the installation member 30 can be improved. Since the base member 40 is rotated from the insertion posture to the fixed posture in a state where the bending portion 55 is in contact with each of the receiving portions 77, 77, the bending portion 55 of the locking protrusion 42 and the locking receiving portion 70 of the locking receiving portion 70 are rotated. It is possible to prevent a load from being applied to each locking receiving portion 70 and to prevent deformation and breakage of the locking protrusion 42 and the locking receiving portion 70.

  Then, when the locking projection 42 is inserted into the insertion portion 76, the arcuate curved portion 55 that is the projection of the locking projection 42 is fitted into the arcuate receiving portion 77 that is concave. Therefore, the locking projection 42 is properly positioned and held with respect to the insertion portion 76. Since the bending portion 55 is in sliding contact with the receiving portion 77 when the base member 40 is rotated from the insertion posture to the fixed posture, the base member 40 can be smoothly and stably rotated.

  Further, since the restricting portion 78 comes into contact with the curved portion 55 of the locking projections 42 and 42 inserted into the insertion portion 76, the locking projection 42 is inserted into the insertion portion 76. Thus, when the base member 40 is rotated from the insertion posture to the fixed posture, the locking projection 42 is restricted from being detached from the insertion portion 76, and the base member 40 to be rotated is prevented from being detached from the installation member 30. Therefore, the fixing operation of the base member 40 to the installation member 30 can be performed easily and appropriately. When the base member 40 is in a fixed posture, the locking projections 42 and 42 and the locking receiving portions 70 and 70 are locked, and the curved portion 55 of the locking projection 42 is restricted. Since the portion 78 is in contact, the locking projections 42 and 42 are restricted from being detached from the insertion portion 76, and the base member 40 can be held on the installation member 30 without rattling.

  Further, the base member 40 is provided with two engaging protrusions 42 and 42 arranged in the vertical direction along the left wall portion 47 of the base member 40, and the installation member 30 is provided in the vertical direction along the insertion portion 76.
